Two Apache Clusters

[DualFusion]

Hi,

I have 5 servers:
1) Loadbalancer/Root
2) Apache node
3) Apache node
4) NFS
5) Mail

And I have been trying to get server1 to transfer data to each Apache node depending on there file type, not just what folder they are in. For example I may want to have PHP go to Apache node1 and Ruby into Apache node2

I have looked at the two tutorials with no success:
http://www.howtoforge.com/set-up-a-l...ter-ubuntu8.04
http://www.howtoforge.com/reduce-apa...pd-debian-etch

Thanks,
Kevin.

Forgot to note that I also want server1 to be DNS. So I basically want a solution that would let me install DNS and would also load-balance between my 2 apache nodes, but will make sure all PHP files go to node1 while all Ruby goes to node2.

Thanks,
Kevin.

**bump bump**

Can't someone help? Please? This is really important and can't continue without this step. I have been stuck with this problem for a couple days now. Any help is much appreciated.

Thanks,
Kevin.

Have you looked in to using squid as a reverse proxy
Squid has options where you can filter by different types of contents.

I finished looking into squid and saw I can do this: (I think)

acl PHP urlpath_regex (.+).php

but I don't know how to redirect them to node1

Look at this example squid.conf that I use. The only difference is that I don't have them set-up by type exceptions, but by domain. Also send a post to their mailing list. There are some really good individuals on their user mailing list.
That are always willing to help. The part where it talks about who is squid a proxy for and the ACL that are related to those servers is what you are going to be interested in. Let me know if it works

Good Luck

Ok, so I would have to install squid onto loadbalance server and do something like this:

http_port 80 accel vhost
forwarded_for on

# Apache Node 1 & 2
cache_peer x.x.x.x parent 80 0 originserver name=apache1
cache_peer x.x.x.x parent 80 0 originserver name=apache2

# Put domains in a file 
acl HostedSites dstdomain "/usr/local/squid/etc/allowed-sites"
http_access allow HostedSites

# Common ACL
acl all src 0.0.0.0/0.0.0.0
acl manager proto cache_object
acl localhost src 127.0.0.1/255.255.255.255
acl to_localhost dst 127.0.0.0/8
acl SSL_ports port 443
acl Safe_ports port 80          # http
acl Safe_ports port 21          # ftp
acl Safe_ports port 443         # https
acl Safe_ports port 1025-65535  # unregistered ports
acl CONNECT method CONNECT

# Mime types
acl php_mime req_mime_type ^application/x-httpd-php$
acl php_mime req_mime_type ^application/x-httpd-php-source$
acl php_mime req_mime_type ^application/x-httpd-php3$
acl php_mime req_mime_type ^application/x-httpd-php3-preprocessed$
acl php_mime req_mime_type ^application/x-httpd-php4$
acl ruby_mime req_mime_type ^application/x-httpd-ruby$

# File extensions
acl php_ext urlpath_regex -i \.php$
acl php_ext urlpath_regex -i \.pht$
acl php_ext urlpath_regex -i \.phtml$
acl php_ext urlpath_regex -i \.phps$
acl php_ext urlpath_regex -i \.php3$
acl php_ext urlpath_regex -i \.php3p$
acl php_ext urlpath_regex -i \.php4$
acl ruby_ext urlpath_regex -i \.rb$
acl ruby_ext urlpath_regex -i \.rhtml$

# Allow/Deny cache_peer_access mime type
cache_peer_access apache1 allow php_mime
cache_peer_access apache1 deny ruby_mime
cache_peer_access apache2 allow ruby_mime
cache_peer_access apache2 deny php_mime

# Allow/Deny cache_peer_access extensions
cache_peer_access apache1 allow php_ext
cache_peer_access apache1 deny ruby_ext
cache_peer_access apache2 allow ruby_ext
cache_peer_access apache2 deny php_ext

# Allow/Deny http_access
http_access allow manager all
http_access allow manager
http_access deny !Safe_ports
http_access deny CONNECT !SSL_ports
http_access deny all
# Where are the localhost and to_localhost ACL's supposed to go?

# Log traffic
access_log /var/log/squid/access.log

Is this good, or would you change anything?

EDIT: Found out I can do mime types using req_mime_type.

Thanks,
Kevin.

I would highly recommend you post to their mailing list I am not a Subject Matter Expert on Squid. So I am not positive that looks correct.
